  • FDA broadened CAPVAXIVE’s US label to cover at-risk children ages 2-17 who completed a primary pediatric pneumococcal series.
  • The vaccine already targets invasive pneumococcal disease in adults; it is given as a single dose.
  • Approval relied on Merck’s Phase 3 STRIDE-13 study, which showed noninferior immune responses versus Pfizer’s PPSV23 for shared serotypes.
